Your First Line of Defense Against Viral Infections
The worldwide pandemic due to the novel COVID-19 coronavirus has brought focus to prevention – both in terms of reducing the risk of infection through “social distancing” and good hygiene as well as measures to bolster the immune system. But even before our immune system comes in contact with a coronavirus or any microorganism, there are natural barriers to infection. As it relates to COVID-19, the first line of defense is the lining of the airways or respiratory tract – nasal cavity, sinuses, throat, trachea, and bronchi.
